This car engine upper radiator hose (radiator to oil cooler line) serves as a critical circulation component for the vehicle's thermal management system. It ensures efficient and reliable coolant routing to the engine block under extreme operational stress.
This part is precision-engineered for the following BMW sedan and touring chassis variants equipped with the N52 3.0L naturally aspirated inline-6 engine:
Established in 2018, Guangzhou Tonghua Auto Parts Co., Ltd. is located in Tanbu Town, Huadu District, Guangzhou—a region known as the "Pearl of the Eight Rivers." Situated at the junction of Guangzhou and Foshan, the company enjoys a prime geographical location and convenient transportation access. It is a large-scale, modern enterprise integrating wholesale operations, sales, and import-export trade, specializing in high-end domestic auto parts and comprehensive vehicle components.

Adopting an integrated "in-house production and direct sales" model, the company eliminates intermediary markups. We strive for innovation, aiming to disrupt the status quo of the domestic auto parts market and transform traditional marketing approaches.

Q1: Can I replace this upper radiator cooling hose by myself?
A1: DIY installation is not recommended. Swapping this hose involves managing spring locking clips, catching old fluids, and executing a meticulous engine block cooling bleed sequence. Trapping air within a BMW system will induce rapid engine overheating. It is highly advised to let a qualified professional complete the job on a completely cold engine.
Q2: How do I guarantee this 17127578399 water pipe fits my 5/7 Series 100%?
A2: BMW engine configurations vary significantly between model years, markets, and engine variations (such as the L4 turbocharged N20 vs. the L6 naturally aspirated N52). For exact assurance, please forward your 17-digit VIN code to our support team before ordering for a precise electronic catalog confirmation.
Q3: When is the right time to preventatively swap this coolant hose?
A3: European engine bays generate high heat loads, accelerating the embrittlement of rubber and plastic fittings. If you find the hose wall hardening, showing tiny exterior structural cracks, or if you spot dried white, pink, or green crusty fluid buildup on the joints, the hose has passed its service life and should be replaced immediately.
